GEARING FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No.333,026, dated December 22 1885.

I Application filed October 1 4. 1885. Serial No. 179,875. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. PATTISON,

a resident of Freeport, in the county-of Stephenson and State of Illinois, have invented- 5 certain new and useful Improvements in Gearings for Windmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in gearings for windmills of the class known as power-mills in contradistinction from pumping-mills.

The invention is fully described and explained in this specification, and shown in the accompanying drawings, in which.

Figure 1 is a central vertical section of a tower on which is mounted one form of the gearing constituting the subject-matter of this application. Fig. 2 is a similar view of a modified form of the gearing. Fig. 3 shows a slightly-modified position of the identical gearing shown in Fig. 1. V

p The arrows on the gears are intended to indicate the same directions of rotation as if the gears wereshown in elevation.

In Fig. 1, A are the posts of an ordinary windmill-tower, and D is a top plate fastened to the posts.

is a turn-table resting on the usual antifriction balls set on the top-plate, D, and cis a horizontal wind-wheel shaft journaled in the turn-table, and provided on its inner end with a rigidly-mounted miter-gear, F.

S is a sleeve dependent from the center of the turn-table, and I is a gear rigidly attached thereto. A preferably-hollow shaft, M, is our-, naled in the turn-table, and has on its lower end a rigidly mounted spur-gear, 3, and on its upper end a rigidly-mounted miter-gear, E, which engages with the miter-gear F on the wind-wheel shaft. At one side of the vertical axis of the mill are two independently-rotating 4 5 power-transmitting vertical shafts, M M,suitably journaled in the tower. The gear-wheel 3 engages with the spur-gear G, rigidly mounted on the shaft M, and the gear-wheel I engages with the spur-gea'r K, rigidly mounted 50 on the shaft Z. A horizontal arm, N, carry- .oated by the arrow thereon.

ing two vertical gudgeons, P, is rigidly connected with the shaft Z and gear K, and on each of the gudgeons P is mounted loosely a a planet-gear, T, engaging with an internal gear, 0, fastened to the shaft M, and also engaging with the spur'gear Q, rigidly fastened to the shaft M.

The operation of this gearing is as follows: If the turn-table, with its sleeve S and gear I, be held stationary, and the wind-wheel shaft 0 and gear F be rotated in the direction indicated by the arrow on the gear, the hollow shaft M, with its gears E 3, turns in the direction indicated by the arrow on either of said gears, and consequently the gear G, shaft M, and gear 0 must turn in the opposite direction, as indicated by the arrows on the gears. The turn-table, the sleeve S, and the gear I being stationary, the gear K, arm N, and gudgeon P are also stationary, and consequently the rotation of the gear 0 rotates the planet-gears T about the respective gudgeons P without revolving them about the vertical axis of the shafts Z M or about the axis of the gear 0. The rotation of the planet-gears T rotates the spur-gear Q in the direction indicated by the arrow thereon, and as the gear Q is rigidly fastened to the shaft M the shaft turns with the gear and transmits the motion of the mill to any mechanism tobe operated. On the other hand, if the power-transmitting shaft M be held stationary, and the turntable be rotated in the direction indicated by the arrow thereon, the sleeve S and gear I turn in the same direction, and the gear K, arm N, and gudgeon P turn in the opposite direction. The shaft M and spur-gear Q being stationary, the rotation of the arm N rolls the planet-gears T about the spur-gear Q, and thus rotates the gear 0 in the direction indi- 0 This rotation of the gear 0 is communicated, through the shaft M and gears G 3, to the hollow shaft M, which is thus made to rotate in the same direction as the turn-table. The relative sizes of the o5 gears are such as to give the shaft M and the turn-table the same speed of rotation, and thus the rotation of the turn-table when the shaft M is at rest turns the shaft M at a speed uniform with that of the turn-table itself, thereby 10o preventing any rotation of the shaft 0 in ,its

bearingin other words, the rotationof the turn-table neither rotates the shaft 0 nor the shaft M, and consequently the, gearing is perfectly balanced and the side draft is obviated.

The gearing shown in Fig.2 is the same as.

that shown in Fig. 1, except that the gear 0 is a spur-gear instead of an internal gear, and the gear Q is an internal gear instead of a spur gear. The only effect of the change is to vary the ratio of the speed of the shaft M to that of the shaft 0, the operation-of the gearingjn all other respects being the same.

The form shown in Fig. 3 differs from that of Fig. 1 only in having the shaft M and gears G O journaled onthe shaft M instead of on:

the Shaft Z.

In mypending application, No. 180,409, I show and describe a gearing similar in many respects to the one forming the subject ofthis application. The two forms differ, however,

in one very important particular In the form shown and described herein the arm N,-

which supports the planet-gear T, 'is' connected, by means of the gears K I,'.with the turntable, and is therefore stationary, exceptwhen the turn-table rotates, whereas in the form set out in the application N 0. 180,409, referred to, the corresponding arm, N, is-connected by suitable gears wit-h the vertical shaft M, and revolves with the rotationof the wind-wheelshaft.

In 'my patent of May 5,1885, I have shown and claimed certain features which are shown:

and described in this application.

Without particularly specifying the features which have been so shown and claimedin said prior patent,I hereby disclaim any novelty for. the features covered by this applicationj except such as is set forth inthe following claims, .to wit:

1. In a windmillof the class described, the

combination of the gear K,located at one side of the vertical axis of the mill, the planet-gear T, whose support is rigidly connected-with and rotated by said gear K, and a gear engaging directly with the gear K and having its.

axiscoincident with the vertical axis of the mill.

2. In a windmill of the class described, the

combination of a rotating turn-tableand a gear-wheel rigidly fastened thereto, a wind wheel shaft journaled in the turn-table, a

power-transmitting gear at one side of-the vertical axis of the mill, and a train of gearing connecting said wind-wheel shaft, turntable gear, and said power-transmitting gear, one element of said train of gearingbeing a loosely-mounted gearifree to rotate on its own axis and to revolve about the axis of rotation of said power-transmitting gear, whereby the rotation of the wind-wheel shaft in its bearing rotates said loosely-mounted gear about its own axis only.

3. The combination of the turn-table G, the

gear I, rigidly mounted on said turn-table, the

gear. K, engaging withthe gear I, and the planet-gear T, Whose support isrigidly connected with and rotated by said gear K, substantially as shown and described, and for the purpose set forth.
